The nursery trays are popping with clam seed. The clams are large enough to be spread out in the sand in rows and covered with nets for the next several years until harvest. As the tide recedes we shake all the sand out of the nursery trays leaving just the clam seed. The trays are brought back to the shop where we can sieve the clams into large and small grades.Barb and Sara are weighing clams to estimate numbers to control planting density. The following day clams are spread in the sand and covered with netting to protect them from predators. The clams will grow from the thumbnail sized seed to littleneck size over the next two years. The planting process will continue during the extreme tides through September and into October if necessary.
